A series of simulations were performed to evaluate the effects of mature size (WMA; 60, 70, 80 and 90 kg), slaughter weight (SW; 55, 60 and 65 kg) and three diets fed to feedlot lambs. Rations included a traditional diet (C2L) or placing weaned lambs on alfalfa for either 30 (A30) or 60 (A60) d before placing them on the C2L diet (A30-C2L and A60-C2L). Two lamb pricing schemes were used in the ...

in this study, the effects of late gestational undernutrition (lgu) on plasma concentration of insulin-like growth factor 1 (igf-i), leptin, insulin and glucose in subsequent sucking lambs was investigated. ten twin-bearing ewes were fed either restrictedly (restricted) or adequately (control) during the last six weeks of gestation and were fed ad libitum after parturition. blood samples were t...

The object of this study is to evaluate the influence of silymarins from cultivated and wild Silybum marianum L. plants with different content of flavonolignans, especially silibinin on serum lipids levels and on the experimental atherosclerosis development in rabbits fed on high cholesterol-diet (HCD). Forty eight male six-months-old white New Zealand rabbits (1.8-2 kg) were randomly assigne...

Data were collected on 130 intact male lambs fed diets based on roughages supplemented with fish meal, soybean meal, or corn gluten-blood meal and slaughtered at 43 kg live weight. A nonsupplemented group served as a control. The lambs represented Romanov (R), Finnsheep (F), a new breed developed in Canada (DLS), Coopworth (C), and Suffolk (S), three first crosses of DLS with R, F, and Booroola...

this study was conducted to evaluate the effect of adding a commercial medicinal plant (mp) powder containing garlic (allium sativum) and thyme (thymus vulgaris) to diets that included olive pulp (op), on the performance and carcass characteristics of broiler chicks. a total of 240 day old male ross-308 broiler chicks were allocated into six iso-nitrogenous and iso-energetic dietary groups with...

20 one-month-old sanjabi suckling lambs (ten males and ten females with initial liveweight of 13.4 ± 1.3 and 11.6 ± 0.9, respectively) were used to assess the effect of ad libitum creep mixture on dry mater intake, live weight gain and carcass characteristics. the lambs were blocked within sex according to their live weight and randomly allocated to one of two treatments, control (free suckling...

1. Forty-eight intact male lambs (30 kg) were fed to gain 16 (H), 5 (M) or -6 (L) kg during a 42 d interval (period 1). Lambs from each of the H and M groups were fed to gain either 16 (HH, MH), 5 (HM, MM) or -6 (HL, ML) kg and lambs from the L group were fed to gain 27 (LS), 16 (LH) or 5 (LM) kg during the ensuing 42 d (period 2). 2. Fasting heat production (FHP) of four lambs from each treatm...

Effects were evaluated of high dietary levels of magnesium oxide (MgO) or limestone on DM, OM and CP digestibility, N balance and intestinal absorption of amino acids by lambs fed a high concentrate diet. Twelve wether lambs equipped with abomasal and ileal cannulas were blocked by weight and breeding and allotted to treatments in a randomized block design in two consecutive trials. Diets were ...

this experiment was conducted to evaluate the effect of camelthorn (alhagi sp.) as a foraghe in the diet of balouchi sheep (during the last two months of gestation and two months of lactation) where 72 ewes in a completely randomized design with three treatments (diets) and four replications were used. experimental diets were : 1) wheat straw 50%, alfalfa hay 30% and barley grain 20%, as contro...

The performance of 12 male and 12 female Mandya Merino lambs weighing between 5.4 and 12.4 kg was investigated by feeding neem seed kernel cake (NSKC) after treatment with 2.5% urea. Lambs of each sex were allotted randomly to concentrate mixture containing either 30% groundnut cake (GNC) or 33% urea-treated neem seed kernel cake (UTNSKC). Over a period of 182 days the concentrate mixtures fed,...
